Shellworks is a London-based biomaterials company founded in 2019 that creates and manufactures Vivomer, a plastic-like material produced by fermenting second-generation feedstocks such as used cooking oil. Vivomer performs like traditional plastic during use but biodegrades after disposal, offering brands a sustainable packaging option. The company has proven cost competitiveness with materials like aluminum and glass even at a relatively small production scale of roughly five million units, removing a key barrier to adoption. Shellworks is targeting the wellness sector first and plans to build a global production network, including blow-moulding facilities in the UK, Europe and the United States, to shorten supply chains and lower carbon footprints. The firm will also develop mass-market partnerships to accelerate market penetration. Longer term, management expects economies of scale to further improve its pricing advantage over petroleum-based plastics.
